Abstract
Purpose
To evaluate long-term arterial patency and abnormalities of bile ducts in patients that had endovascular treatment for arterial complications after liver transplantation (LT).
Materials and Methods
Between 2004 and 2014, 1048 LTs were consecutively performed in our institution and 53 patients (42 men; age range 19–69) were diagnosed and treated by endovascular techniques for arterial complications such as stenosis, thrombosis, dissection or kinking of the hepatic artery (HA). Radiological and surgical data were retrospectively analyzed, and survivors were contacted to undergo follow-up Doppler ultrasound (DUS) of the HA and magnetic resonance cholangiopancreatography.
Results
The primary technical success of endovascular treatment was 94% (n = 50). The patency rate of HA at 5-year was 81%. After a median follow-up of 58 months, 17 patients (32%) developed radiological features of ischemic cholangiopathy (IC), including 7 patients with abnormal DUS and 10 with normal DUS. Patients who presented with complications of the HA in the first 3 months after LT developed IC more frequently (42%) than others (12%) (p = 0.028). No other factor was associated with the development of IC.
Conclusion
IC was more often observed when HA complication occurred within the first 3 months after LT. The presence of IC was not excluded by a normal DUS during follow-up.
